Abstract

The present invention relates to an air purifying apparatus that includes a casing, an orientation air deflector disposed on the casing, a movable air deflector included in the casing and disposed at a position corresponding to the orientation air deflector, a plasma reactor disposed at the bottom of the movable air deflector, an electric function controller having an anion circuit and a plasma circuit therein and disposed at the bottom of the plasma reactor, a fan box having a fan installed therein and disposed at the bottom of the electric function controller, and a power switch disposed at the bottom of the casing. The air purifying apparatus can achieve the effects of sterilizing, disinfecting, and deodorizing air.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention: [0002] The present invention relates to an environmental protective home electric appliance product, and more specifically to a plasma nano catalytic disinfecting and purifying apparatus that integrates the technologies of pulse high-voltage plasma, anion transmitter, and nano catalysis. [0003] (b) Description of the Related Art [0004] In the environmental protective products, an air purifier becomes a popular appliance and has a tremendous market potential. The present air purifiers include anion air clarifiers, ozone air purifiers, ultraviolet air purifiers, photocatalytic air purifiers, and plasma air purifiers, and products that integrate different kinds of purifiers. In the comparison of the working efficiency and functions of the aforementioned purifiers, ozone and photocatalytic air purifiers are the most superior ones, but there still exists the shortcomings of a complicated structure and a low performance.

AI Technical Summary

Benefits of technology

[0017] The beneficial effects of the present invention include its extensive applications in different areas including hospitals, offices, food industry, computer room, public places and families, etc. For disinfection and sterilization, and prevention of cross infection, the microorganism retaining rate is up to 95% (for two hours). The price of a fan filter unit having a similar effect as the air purifying apparatus of the invention is several times of the air purifying apparatus of the present invention, and the effect of purifying aerosol particles of microorganisms falls in the range of 0.1 μm˜0.5 μm. If the aerosol particle size is smaller than 0.1 μm, the high-performance filter installed in the fan filter unit no longer functions properly. The filter of the fan filter unit creates a large resistance to the air, and thus affecting the efficiency of the air purification. In addition, it is necessary to replace the filter regularly. As we know that the size of microorganism's aerosol particles is approximately 0.002 μm˜30 μm, and the size of bacteria is approximately 0.25 μm˜20 μm, and the size of viruses is approximately 0.002 μm˜0.30 μm, and thus the fan filter unit has a good capability for effectively filtering bacteria, but it is unable to filter viruses. The present invention can collect tiny particles at the level of 0.01 μm˜0.00 μm, and also has a more powerful disinfecting strength than that of the fan filter units. The invention concurrently has the functions of purifying various different organic matters and ammonium toxic gases. If different toxic gases are filled into a space of 22.5 μm3, the concentration of each gas in equilibrium is given as follows: 4.14 mg / m3 for formaldehyde, 9.37 mg / m3 for benzene, 8.09 mg / m3 for toluene, 5.04 mg / m3 for xylene, and 6.65 mg / m3 for ammonium, and the purifying rate for each gas after 180 minutes of purification is given as follows: 76.6% for formaldehyde, 87.8% for benzene, 91.8% for toluene, 93.6% for xylene, and 92.9% for ammonium. Thus, the present invention can achieved the expected objectives.
